I guess the series is definitely taking a more 'mature' route, then.
Incidentally I'm surprised actually how many younger players of DMC there are, or how many people play it with their younger siblings or kids nearby. I've always thought it was a fairly dark game and always contained 'mature' elements. The 'Hell' level alone in DMC1 would have been enough to have give me nightmares as a kid, with the giant heart and all those pulsating veins and doors that look like flesh diaphragms. The other games, too, contain moments of focused gore or violence I don't think wouldn't leave an impression on a kid, such as Dante being impaled or someone being cold-bloodedly murdered, etc.
I suppose it's this idea of games being something that kids take interest in and play, so it's inconvenient if a title starts to become more mature - which is quite a widely expressed viewpoint - but one I find kind of baffling. I view games as entertainment on the same level as movies now, and there are some movies I wouldn't let my kids or younger siblings watch simply because I know how much they can affect them (my parents didn't care, and I watched The Thing when I was six. Cheers for that, guys, 'cause I wish I hadn't). Maturity of games is something we're all just gonna have to deal with, I think.
The changing of Dante's character for something more brazen though is another matter, and one of personal taste, I guess.
